Merge pull request #63 from kyrsjo/make_nohardpath

Delete if statement hardcoding specific -L path for unrecognized gfortran versions (not 4.4 or 4.5) - the linker should figure it out itself.

The patch is tested patch on CC7.2.1511 (virtualBox, gfortran 4.8.5), SLC6.7 (lxplus, gfortran 4.4.7), Fedora23 (gfortran 5.3.1), Ubuntu 15.10 (virtualBox, gfortran 5.2.1) and it works without any problems.
